REMOVABLE WINDOW -SASI-I.

Specication of Letters Patent No. 19,301, dated February 9, 1858.

To all whom it may concern:

Be it known that I, ROBERT H. KIRCK, of Utica, in the county of Oneidaand State of New York, have invented a new and useful Improvement inWIindows; and I do hereby declare that t-he following is a full, clear,and exact description of the same, reference being had to the annexeddrawings, making a partof this specification, in which- Figure l, is afront view of a window constructed according to my invention. Fig. 2, isa transverse vert-ical section of ditto. Fig. 3, is a horizontal centralsection of ditto. Fig. 4, is a detached top view of the lower sash ofditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an improvement in that class of windows thesashes of which rise and fall, or any window the sash or sashes of whichare secured in their frame or casing by parting beads and stop strips.

The object of 4the invention is to admit of the sashes being removedfrom their frame or casing without detaching the parting beads and stopstrips. This object is attained by having the sashes jointed at theircenters, and provided with a suitable catch as hereinafter shown.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents the frame or casing of an ordinary window the sashes ofwhich rise and fall. This frame or casing is of the usual form and isconstructed in the usual way, with the exception that the parting beads(a) and stop strips (b), which form the grooves (o) in which the sashesslide are permanently attached to the sides (fl) of the frame or casing.The parting beads (a) and stop strips (b) may be made detached and thensecured to the sides (d), but I prefer rebbeting out the grooves (o) sothat the beads and strips and side pieces (d) of the frame or casingwill be each formed out of one piece of stuff.

B, is the upper and C, is t-he lower sash. Each sash is constructed witha vertical center strip (e) technically termed munnion or mullion. Themunnions or mullions are divided vertically into two-equal parts and areconnected by joints or hinges The lower sash C is provided at its upper'part with a catch This catch may be constructed in any proper way toprevent the lower sash from casually folding inward as indicated byarrow l, the joints or hinges (f) permitting the sashes to fold only inthis direction.

From the above description it will be seen that when the catch (g) isunfastened and the sash C folded inward as indicated in Fig. l, saidsash may be removed from the frame or casing A, and it will also be seenthat when the lower sash is removed, the upper one B, by being drawndown a trilie so as to be out of the upper groove (7L) may also befolded inward and removed from the frame or casing. The upper sash B,does not require a catch as it is prevented from folding casually by thelower sash.

By this improvement the sashes may be removed from and fit-ted in thecasing with the greatest facility, and sashes frequently require to .beremoved from their casing to be washed, repainted, glazed, &c. To removethe sashes of ordinary windows from their frame or casing the partingbead (a) and stop strip (7)) at one side of the frame or casing requireto be removed, and the paint soon becomes soiled and the bead and stopstrip disfigured by being repeatedly removed from and renailed to the.casing, this difficulty is avoided by the within described invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is,

J ointing the sash or sashes'of a window at the center substantially asherein described, so that they may be removed from the casing withoutdetaching the parting beads or stop strips, the sash or sashes beingprovided with a catch or any equivalent device to prevent the casualfolding of the same.
